How does a drawdown retainer work?
The client pays a fixed amount at the start of the period, typically monthly. As the team logs approved hours, each hour reduces the balance at the contracted billing rate. When a deliverable-based drawdown is used instead, each shipped item reduces the balance by its list price. At the end of the period the agency issues a usage statement showing the opening balance, what was drawn, and what remains.
The cap is the pre-paid balance itself. Work stops, or an overage is arranged, when the balance reaches zero. This is the difference from a flat retainer, where the fee is fixed and the hours are a scope that the agency polices by hand. The drawdown model makes the limit arithmetic rather than judgment.
How should overages on a drawdown retainer be handled?
The rule that protects the agency is approve and pay before the work happens. When the balance is projected to run out before the period ends, the account manager sends an overage quote for the additional hours at the overage rate, the client approves it, the agency invoices it, and the work proceeds once paid or at least once approved in writing. Work done first and billed later becomes unbilled work that clients dispute.
The overage rate is usually the standard billing rate or 10 to 15% above it, since the pre-paid balance earned a commitment discount and the overage did not. Some agencies allow a small grace band, such as 5% of the balance, to be invoiced with the next period rather than stopping work over a few hours. The band should be written into the contract.
Verbial tracks the drawdown balance from approved time entries and can invoice pre-paid overages before the extra hours are logged.
What rollover policy should a drawdown retainer have?
Rollover determines what happens to an unused balance. The three common policies are no rollover, where unused funds expire at period end; capped rollover, where up to a fixed share such as 20% carries forward for one period; and full rollover, where the balance accumulates indefinitely. Full rollover is the most client-friendly and the most dangerous, because a client can bank six months of unused hours and then demand them all in one month the agency has not planned for.
Capped rollover with an expiry is the usual compromise. It gives the client some flexibility for a light month without creating an open-ended liability. Whatever the policy, unused funds under a rollover clause stay on the balance sheet as deferred revenue until they are used or expire, so the policy has accounting consequences as well as capacity consequences.
- No rollover: cleanest accounting, highest client friction
- Capped rollover, 20% for one period: flexible, bounded, the common default
- Full rollover: avoid, or pair with an expiry of 90 days and a capacity notice period
What should a drawdown usage statement show?
The statement is the document that keeps the model honest with the client. It should show the opening balance, hours drawn by person or department with dates and descriptions, the rate applied, any approved overages, the closing balance and any amount rolling over. Many agencies send it with the next period's advance invoice so the two are read together.
Frequency matters as much as content. A monthly statement is the minimum, and a mid-month balance alert at 75% consumed gives the account manager time to arrange an overage before the balance hits zero. Clients rarely object to overage invoices they saw coming two weeks earlier.
Worked example
A 12-person agency sets a client up on a $15,000 monthly drawdown retainer at a $150 blended billing rate, so the balance covers 100 hours. By August 20 the team has logged 88 approved hours, drawing $13,200 and leaving $1,800, or 12 hours. The account manager forecasts 22 more hours of work before month end, 10 beyond the balance, and sends an overage quote for 10 hours at $150 = $1,500. The client approves and pays on August 22, and the work proceeds. The August statement shows $15,000 opening, $16,500 total funded, 110 hours drawn at $150 = $16,500, and a $0 closing balance. Had the client used only 80 hours instead, the $3,000 unused would have been subject to the contract's 20% rollover cap, so $3,000 carries to September (within the $3,000 cap) and the September opening balance would be $18,000.
Questions
What is the difference between a drawdown retainer and a regular retainer?
A regular retainer is a fixed fee for a scope of service, and the hours inside it are a guideline the agency enforces. A drawdown retainer is a pre-paid balance that hours consume at a rate, so the limit is exact and the client can see it. The drawdown model shifts overrun risk from the agency to the client.
How is drawdown retainer revenue recognized?
As the balance is consumed. The pre-paid amount is deferred revenue when received, and each approved hour moves its value at the billing rate to revenue. Unused funds stay deferred until used or until they expire under the rollover policy, at which point they are recognized.
Should a drawdown retainer be priced at the standard billing rate?
Usually at a small discount to the standard rate, 5 to 10%, in exchange for advance payment and commitment. The overage rate above the balance should be the standard rate or higher, so the client has a reason to fund the balance accurately rather than under-fund and overage every month.
